Britain\u2019s renewable output grew 27% last year, and would have been sufficient to power the entire country 60 years ago.<\/strong> <\/h3>\n\n\n\n

This year\u2019s renewables produced more than the country\u2019s annual electricity demand in 1958. At the height of Beatlemania in 1964, electricity use had risen sharply, but putting this year\u2019s renewables and nuclear together could have powered Britain without fossil fuels.<\/p>\n\n\n\n\n\n\n\n

Renewable energy surged in 2017 thanks to windier weather and more capacity coming online. Of the 294 TWh of grid-supplied electricity consumed in Britain, a quarter came from biomass, hydro, wind and solar plants. Electric Insights recorded 73 TWh of renewable output from plants which operate in the electricity market or export to the national grid. Adding on the many smaller \u2018embedded generators\u2019 which produce electricity locally,1<\/a><\/sup> the renewable total rises to 96 TWh.2<\/a><\/sup><\/p>\n\n\n\n

In 1958, Britain\u2019s 52 million people consumed a little less than this \u2013 91 TWh. The year that brought us Blue Peter, \u201cA Bear Called Paddington\u201d and the Hula Hoop could have been powered by today\u2019s renewable electricity \u2013 averaged over the year. At the time, 92% of electricity came from coal, and the power system emitted 93 million tonnes of CO2<\/sub>. Last year, Britain\u2019s renewables produced as much electricity with just 3 million tonnes of emissions (due to processing and importing biomass).<\/p>\n\n\n\n

Of course, producing the same amount of energy over the year is very different to balancing the nation\u2019s electricity demand hour by hour. Running the country on renewables and nuclear would need tremendous support from integrating technologies (energy storage, responsive demand and interconnection) \u2013 but still, this shows just how far clean energy has come in Britain.<\/p>\n\n\n\n

Britain\u2019s electricity generation mix since 1940 (left). Dotted lines show how last year\u2019s renewable output equalled total demand in 1958; and total low-carbon output equalled demand in 1964. Breakdown of Britain\u2019s electricity mix in these three years show how much electricity supply has diversified (right).<\/em> <\/p>\n\n\n\n
